1 Specification of Letters Patent. "Patented A r. 25 1922 Application filed January 20, 1921. 7 Serial No. 438,724.

To all whom it may concern: I

Be it known that I, FRANCIS LEVITT IMPEY, a subject of the King of Great Britain and Ireland, residing at Kalamazoo Works, Northfield, in the-county 10f ,VVarwick, England, have invented certain new v and useful ImprovementsRelating to sup ports for Loose-Leaf Books, of which the following is a specification.

This invention relates to supports used in conjunction with loose leaf books of the type in which a binding bar is hinged to one edge of each of the covers and in which'the leaves are positioned by postsinsertedmto the binding bars through holes in the leavesr With the book opened out. and the leaves divided into twotparts which respectively 7 rest with the covers of the book on the two parts of thesupport, it is found that owing to tilting of the operative surfaces of the binding bars relatively to the adjacent faces of the covers and leaves lnconvenience' 1s often experienced in rte-engaging theposts with the bars.

avoid this inconvenience in a simple manner,

and for this purpose the invention comprises the use with the support, of one or more trough like or equivalent sockets, holders or other retaining devices for the binding bars, which devices secure the said bars in the proper relationship with the covers and leaves of the book.

The invention also comprises the combine tion with the support,of means coacting with the binding bars forholding them firm ly in the said retaining devices.

Referring to the accompanying sheet of explanatory draw1ngs:-

F lgure 1 1s a' dlagrammatic side elevation showing a book support provided with this site sides of which rest the adjacent edgesof the leaves 6, at or near the junction of each part a. b and the abutment is arranged a trough like holder f, socket or its equivalent for the reception and engagement of the The objectof the present invention is to binding bar g. By'means of thisdevice the bindingbar is not permitted to move relatively tothe cover or leaves and consequently the face of the binding bar is kept normal to holes inthe leaves, and the securing posts it can therefore be readily inserted. The

adjacent sideof. the abutment may bevprovl'ded wlth any convenient spring or other catch a which can be caused to engage the upper slde of the-binding bar and secure it firmly within the trough.

In the lattervcase'the arrangement of the f trough is "such that when the adjacent cover support is adjusted 'g to the desired inclination the trough moves with it, so that there is no relative movement between the trough and the said part.

When the catch i is used the said slots in the leaves give the required accessffor'the catch tothe upper surface of the clamping barf Having thus described my invention what I claim as new and ters Patent is I v r r In a support for loose leaf books the come bination of a pair of members on which thecovers of a book are carried, an intermediate abutment, trough like retaining devices on said members for the bindingbars'of the book covers, projections on the outer faces of the abutment adapted to enter notches in "the 1ea ves,-and;means sliding within said projections for engaging the binding bars,

substantially as described. 7 I
